Abstract
The invention discloses a kind of quick method for reducing Friction Coeffcient of Polyurethane Elastomers, by coating a kind of surface conditioning agent on polyurethane elastomer surface, then one layer of compound that can reduce coefficient of friction is formed in surface by hydrolytic condensation, the method of the present invention is applied to all polyurethane elastomers, original material and structure need not be changed, rapid and convenient, production cost can be substantially reduced, improve efficiency.
Description
Technical field
The invention belongs to technical field of polyurethane elastomer, more particularly to a kind of quick reduction polyurethane elastomer friction system
Several methods.
Background technology
Polyurethane elastomer is a kind of adjustable speciality polymer synthetic material of hardness.The characteristics of due in its structure, its
Coefficient of friction is significantly larger than the materials such as polytetrafluoroethylene (PTFE), ultra-high molecular weight polyethylene, using polyurethane elastomer as driving section
Part or seal member using when there is because coefficient of friction is excessive cause big heat amount, rapid wear the problem of, so as to lead
Cause the premature failure of polyurethane material and ineffective so that the superior abrasion resistance of polyurethane elastomer can not fully demonstrate
Come.Although the purpose of reduction coefficient of friction can be reached by adjusting formula, complex process, technical process requirement is compared
Strictly.
The content of the invention
The problem of existing for prior art, it is an object of the invention to provide a kind of quick reduction polyurethane elastomer friction
The method of coefficient.The present invention by coating a kind of surface conditioning agent on polyurethane elastomer surface, then by hydrolytic condensation in
Surface forms one layer of compound that can reduce coefficient of friction.
To achieve these goals, the present invention uses following technical scheme：
A kind of method for reducing Friction Coeffcient of Polyurethane Elastomers, comprises the following steps：Applied on polyurethane elastomer surface
Cover surface conditioning agent.
Preferably, the surface conditioning agent is prepared by the following component counted in parts by weight：
100 parts of coupling agent,
Solvent 50-100 parts,
Distilled water 50-100 parts.
It is further preferred that the coupling agent is selected from least one of KH550, KH560 and KH570.
It is further preferred that the solvent is selected from least one of dimethylbenzene, isopropanol, ethyl acetate and acetone.
It is highly preferred that it is 1-3 by weight that the solvent, which is dimethylbenzene and isopropanol,：1-5 mixed solvent.
In a kind of embodiment, the method for reducing Friction Coeffcient of Polyurethane Elastomers, comprise the following steps：
(1) it is the surface treatment of polyurethane elastomer is clean；
(2) surface conditioning agent is proportionally allocated；
(3) polyurethane elastomer is soaked in 1-5min in surface conditioning agent, then takes out to be placed in and place 10- at room temperature
30min；
(4) it will be placed in by step polyurethane elastomer in 70-90 DEG C of baking oven and handle 20-40min, and be subsequently placed in 100-
120 DEG C of processing 1-2h are the polyurethane elastomer that can obtain coefficient of friction reduction.
A kind of surface conditioning agent, including the following component counted in parts by weight：
100 parts of coupling agent,
Solvent 50-100 parts,
Distilled water 50-100 parts.
Preferably, the coupling agent is selected from least one of KH550, KH560 and KH570.
Preferably, the solvent is selected from least one of dimethylbenzene, isopropanol, ethyl acetate and acetone.
It is further preferred that it is 1-3 by weight that the solvent, which is dimethylbenzene and isopropanol,：1-5 mixed solvent.
Beneficial effects of the present invention：
The method for the quick reduction Friction Coeffcient of Polyurethane Elastomers that the present invention uses, suitable for all elastic polyurethanes
Body, without changing original material and structure, rapid and convenient, production cost can be substantially reduced, improve efficiency.
